Abstract
A circuit module includes: control object circuits which start operations when a power supply voltage reaches a target value; a current sink circuit which consumes a current supplied thereto; and a power supply activation control unit which increases the current flowing into the current sink circuit at a predetermined rate before starting the operations of the control object circuits and which starts the operations of the control object circuits and simultaneously blocks the supply of the current to the current sink circuit in a case where an amount of the current flowing into the current sink circuit is equivalent to an amount of current to be increased by starting the operations of the control object circuits when the power supply voltage reaches the target value.
